ByteRank – JS Code Challenges

ByteRank turns your daily coding practice into a game.

Every day a new JavaScript challenge drops. Solve it, submit your code, and watch it run against real test cases on the server. Then get a score from Claude AI on the quality of your solution — not just whether it worked, but how clean, efficient, and idiomatic your code is.

Every submission earns you XP. The better your code and the faster you solve it, the more you earn.

── RANK UP ──

Climb seven developer ranks: Rookie → Junior → Mid-Level → Senior → Staff → Principal → Legend. Each rank has its own color and badge. Hit a new rank and the app celebrates it.

── KEEP YOUR STREAK ──

Solve a challenge every day to build your streak and unlock a streak multiplier that boosts your XP. Earn a Streak Shield at 7 days — it protects your streak if you miss a day.

── CHALLENGE YOUR FRIENDS ──

Send async head-to-head challenges to friends on any problem. They have 48 hours to beat your score. Best submission wins.

── COMPETE GLOBALLY ──

The global leaderboard ranks every player by total XP in real time. See where you stand.

── BROWSE THE LIBRARY ──

Not just daily challenges — browse a full library of problems by category and difficulty. Retry ones you've done. Attempt ones you skipped.

── BUILT FOR DEVELOPERS ──

Dark theme by default. Monospace code editor. No fluff.

ByteRank is free to download and play.
